"WebAlkanes: Chlorination II. Introduction: This experiment serves to familiarize us initially with the properties of alkanes (CnH2n +2) which are for the most part very stable, non reactive molecules. Using a process known as free-radical substitution, however, we can create a situation in which a pair of halogen atoms such as Br2or " - Alkane chlorination

WebAlkane. In organic chemistry, an alkane, or paraffin (a historical trivial name that also has other meanings ), is an acyclic saturated hydrocarbon. In other words, an alkane consists of hydrogen and carbon atoms arranged in a tree structure in which all the carbon–carbon bonds are single. [1] Alkanes have the general chemical formula CnH2n+2. WebAlkanes can undergo free-radical substitution in which a hydrogen atom gets substituted by a halogen (chlorine/bromine) Since alkanes are very unreactive, ultraviolet light …
